Generalizing the place-value system to include decimals to the thousandths place ( three places after the decimal), and calculating (add, subtract, multiply, and divide) with decimals to the hundredths place (two places after the decimal)

Problem solving: Understand how to use the place value system to solve real life problems involving adding, subtracting, multiplying and dividing multi-digit numbers

Multiplying whole numbers quickly and accurately, for example 1,638 × 753 using the standard algorithm, and dividing whole numbers in simple cases, such as dividing 6,971 by 63 using partial quotients and area model.

Using equivalent fractions as a strategy to add and subtract fractions; adding and subtracting fractions with unlike denominators; multiplying & dividing fractions by whole numbers/fractions

Understand how to use equivalent fractions to solve real life problems that represent situations of adding to, taking from, and comparisons. Understand how to multiply and divide fractions by a whole number in real life situations involving equal groups of objects, arrays of objects, and comparing

Students extend their whole number work with adding and subtracting and multiplying and dividing situations to decimal numbers and fractions.
